1. Give an everyday example that illustrates the difference between acceleration and velocity. Give an example of uniform and accelerated motion. An everyday example of the difference between acceleration and uniform motion would be for acceleration driving a car down a long straight road, the speedometer is not moving, the needle is on 40 mph, your moving at a constant speed, but the needle isn’t stationary on the speedometer scale because maybe your foot is either on the gas or brake and your

a mining proposal. This new venture is to mine precious metals, specifically ore on a property that, until recently was too small to be considered economically viable. Recent developments in technology have enabled the mining of smaller properties, making it cheaper and more economical. This property can be mined for 20 years producing 1,500,000 tonnes, with the expected yield being 0.05 %( for every tonne = 0.5 kilograms of precious metal). A mining engineer estimated equipment and plant at 38

produced: copper, gold, silver, lead, zinc, tin, molybdenum, iron, cadmium, mercury, selenium, indium and other metals. It is the region’s top producer of zinc, tin, lead and gold, and occupies second place in the production of copper, silver, molybdenum, mercury, selenium, cadmium and phosphoric rock. Currently, Peru has a sufficient reserve of minerals to generate a constant flow of metal production for several decades. The high rates of production have attracted a large amount of inbound investment

ways to control its generated output. Almost any liquid or moist object that has enough ions to be electrically conductive can serve as the electrolyte for a cell. This homemade battery is based on two different metals suspended in an acid solution. You’ll need two different kinds of metal, like copper and zinc nails and some acid liquid. The copper is the + and the nail is the -. The electrons travel from the – through the vinegar (acid) to the + and creates an electric current. A c k n o w l

I have grown up in Crested Butte my whole life, raised my four children between the ages 6-16 and I also married my husband here. As a lifelong resident of Crested Butte I believe that the Red Lady mining operation will benefit our community. Yes it has some negative effects to it, everything we do has a downside. We must look at the good and bads, outweigh the positive and negative effects of our actions. As a mother of four and a wife to a traveling construction worker I believe that the Red Lady

solid metal; it’s soft, silvery-white, with a low melting point and reactive. Many of its physical and chemical properties are more similar to those of the alkaline earth metals than to those of its own group. | Sodium | Chemical element, symbol: Na, atomic number: 11 and atomic weight 22, 9898. It’s a soft metal, reactive and with a low melting point, with a relative density of 0, 97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. |

Metal forming is a general term, for a large group, that includes a wide variety of manufacturing processes. Metal forming processes are characteristic in that the metal being processed is plastically deformed in order to shape it into a desired geometry. In order to plastically deform a metal, a force must be applied that will exceed the yield strength of the material. The material actually gets stronger the more it is deformed plastically. This is called strain hardening or work hardening. Many
